firstly, mixing isopropanol and dearomatized solvent oil at normal temperature to uniformly mix the isopropanol in the dearomatized solvent oil to prepare a treatment mixture;
step two, when the temperature of the surface of the electric appliance is reduced to the normal temperature after the fire disaster, selecting a treatment mixture as a reaction raw material, and covering the surface of the electric appliance after the fire disaster by dipping with a brush or spraying the treatment mixture with a spraying can under the normal temperature condition, so that the dearomatized solvent oil is used as the aerosol mixture reaction catalyst containing smoke particles attached to the surface of the electric appliance in the fire disaster;
after a plurality of seconds of reaction, the mixture of the smoke particles on the surface of the electric appliance and the treatment mixture react at normal temperature and volatilize rapidly;
and step four, wiping the surface after the reaction by using dust-free cloth or dust-free paper, so that the metal compound is wiped off completely.
Further, in the step one, the isopropanol and the dearomatization solvent oil are uniformly stirred, and the dearomatization solvent oil is poured into the isopropanol to prevent excessive contact of the isopropanol with water vapor in the air after the sequence is reversed.
Further, the ratio of the isopropanol to the dearomatized hydrocarbon solvent oil in the first step is 1:1-1: 3.
Further, the ratio of the treatment mixture to the mixture of the smoke particles on the surface of the electric appliance in the step two is 2: 1.
Further, in the fourth step, the dust-free cloth or the dust-free paper is wiped off, so that the smoke particle mixture is wiped off, and the part to be volatilized of the isopropanol is further volatilized, so that the surface of the electric appliance is wiped off.
Compared with the prior art, the invention has the following beneficial effects:
the method provided by the invention can be used for performing a covering reaction between the treatment mixing agent and the grey white powdery metal compound on the surface of the electric appliance, so that the reaction efficiency of the grey white powdery metal compound on the surface of the electric appliance is improved, meanwhile, the solvent amount ratio between the treatment mixing agent and the grey white powdery metal compound on the surface of the electric appliance is 2:1, so that the reaction efficiency is improved, in addition, in the treatment process, hydrolysis reaction is performed between water generated by the reaction and isopropanol, so that the aromatic hydrocarbon removal oil melting agent after the reaction and an isopropanol solution are subjected to an emulsification reaction while the metal compound is dissolved, and a large amount of cleaning operation is avoided.
